What I’ve built

The tools

Each tool solves a job I was doing by hand before I wrote it. One-time payment, no subscriptions. More tools are on the way.

Amazon KDP

PuzzleKit

Builds complete puzzle books — Sudoku, word search, mazes and memory games — with bleed, margins and page counts already correct for KDP. Commercial and PLR rights included.

Something is always half-built

More tools are coming. If you want to hear when the next one opens — or you have a list and you want to promote it — email me. You get me, not a support queue.
